9 / 29 page Manual epc10x Figure 7: Message Structure 3.2 Bus Wire Considerations The electromechanical design of a system using multiple epc10x devices on a twisted pair cable with an impedance of typically 100 Ohms has an impact on the overall impedance of the system. Figure 8shows the change of the cable impedance with smaller element pitch. 1.0 1.8 3.2 5.6 10.0 17.8 31.6 56.2 100.0 0 20 40 60 80 100 120 Pitch [cm] Figure 8: Line impedance as a function of the element pitch on a 100 Ohm twisted pair cable On the source side the termination is done by the resistor RTE (see Figure 2). On the other side it is highly recommended to terminate the bus line with an AC terminator network (shown in Figure 9) which matches the overall impedance of the system according to Figure 8. In order to avoid high DC currents in the termination resistor, a capacitor of 100nF should be connected in series to the termination resistor. The interface device has to be placed near the L/R circuit. © 2013 ESPROS Photonics Corporation Characteristics subject to change without notice Page 9/29 Manual epc100 - V2.3-DRAFT 130812 www.espros.ch Figure 9: Bus termination network R TE C TE A 0 A1 A2 A3 A4 A5 A6 A7 A8 A9 C0 C1 C2 P0 P1 P2 P3 P4 P5 P6 P7 P8 P9 Device Address Command Parity Bits A 0 A1 A2 A 8 A9 C 0 C1 C2 P0 P1 P 8 P9 R0 R1 R2 R3 R4 D0 D1 D 14 D15 P0 P1 P 8 P9 Device Address Command Parity Bits Parity Bits Data Register P 0 P1 P 8 P9 Parity Bits D 0 D1 D 9 D10 Data A 0 A1 A2 A 8 A9 Device Address R 0 R1 R2 R3 R4 D0 D1 D 14 D15 P0 P1 P 8 P9 Parity Bits Data Register Normal Command Write Command Results Register Readout C 0 C1 C2 A 0 A1 A2 A 8 A9 Device Address R 0 R1 R2 R3 R4 Register P 0 P1 P 8 P9 Parity Bits Command Read Command |
